Ordered sapphire beads from eternal quartz on July 2nd and they finally arrived yesterday. Wish ruby ones were in stock.
I put one in the liger and so far, loving it. I notice even more flavor out of terpy stuff and everything vaporizes more efficiently. Before, I'd see some pooling at my usual 530 - 540F(PID) temps, but with one bead, there is little to no visible oil in the insert. Just brown-ish residue on the walls when you swab with a qtip.
Question for those who tried using the beads with a torch setup, can you heat up a quartz bucket with sapphire/ruby beads inside without them cracking?
On a side note,
I've had my new 11.4g(57 carat) 30mm sapphire insert for a month now, and I'm not noticing any difference from my old 14.2g(71 carat) one.
